We consider transformations of the 2 Ã— 2 propagator matrix in real-time finite-temperature field theory, resulting in transformed nâ€“ point functions. As special cases of such a transformation weâ€¦ (More)

We examine the calculation of the critical temperature T c for the restoration of a spontaneously broken symmetry. Motivated by a set of recently developed gauge dependence identities, we give aâ€¦ (More)

Recent studies of the high temperature soft photon production rate on the lightâ€“cone using Braatenâ€“Pisarski resummation techniques have found collinear divergences present. We show that there exist aâ€¦ (More)
